[36] Some of the first computers that might be called "personal" were early minicomputers such as the LINC and PDP-8 , and later on VAX and larger minicomputers from ...
Key home computers in the early part of the decade predominantly use processors developed in the 1970s. Versions of the 6502, first released in 1975, powered the Commodore 64, Apple II, BBC Micro, and Atari 8-bit computers. The 8-bit Zilog Z80 (1976) is at the core of the ZX Spectrum, MSX systems and many others.

Most people in industrialised countries own more computers in embedded systems in their car and house, than on their desks.

The first aids to computation were purely mechanical devices which required the operator to set up the initial values of an elementary arithmetic ...
